append_cr(), remove_cr(), q_to_nul() and q_to_cr() are defined in multiple

The use of remove_cr() in t0020 to test for a CR is replaced with a new
function has_cr() to accurately reflect what is intended (the output of
remove_cr() was being thrown away).

This patch introduces parts of a Python package called

No actual remote helpers are part of this patch, this patch only
includes the common basics needed to start writing such helpers.
The patch includes the necessary Makefile additions to build and
install the git_remote_helpers Python package along with the rest of

This patch is based on Johan Herland's git_remote_cvs patch and

vim, for example, is happy to assume a terminal supports ANSI

The tests generate a large amount of I/O activity creating

time it takes to run the test suite by creating trash
directories on filesystems with better performance
characteristic, even though we may not want the rest of the
git repository on those filesystems (e.g., because they are
not network connected, or because they are temporary
ramdisks).
For example, on a dual processor system:
$ cd t && time make -j32
real 1m51.562s
user 0m59.260s
sys 1m20.933s
# /dev/shm is tmpfs
$ cd t && time make -j32 GIT_TEST_OPTS="--root=/dev/shm"
real 1m1.484s
user 0m53.555s
sys 1m5.264s

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7

Some tests can be run only if a particular prerequisite is available. For
example, some tests require that an UTF-8 locale is available. Here we
introduce functions that are used in this way:
1. Insert code that checks whether the prerequisite is available. If it is,
call test_set_prereq with an arbitrary tag name that subsequently can be
used to check for the prerequisite:
case $LANG in
*.utf-8)
test_set_prereq UTF8
;;
esac
2. In the calls to test_expect_success pass the tag name:
test_expect_success UTF8 '...description...' '...tests...'
3. There is an auxiliary predicate that can be used anywhere to test for
a prerequisite explicitly:
if test_have_prereq UTF8
then
...code to be skipped if prerequisite is not available...

Many tests pass $(pwd) in some form to git and later test that the output
of git contains the correct value of $(pwd). For example, the test of
'git remote show' sets up a remote that contains $(pwd) and then the
expected result must contain $(pwd).
Again, MSYS-bash's path mangling kicks in: Plain $(pwd) uses the MSYS style
absolute path /c/path/to/git. The test case would write this name into
the 'expect' file. But when git is invoked, MSYS-bash converts this name to
the Windows style path c:/path/to/git, and git would produce this form in
the result; the test would fail.
We fix this by passing -W to bash's pwd that produces the Windows-style
path.
There are a two cases that need an accompanying change:
- In t1504 the value of $(pwd) becomes part of a path list. In this case,
the lone 'c' in something like /foo:c:/path/to/git:/bar inhibits
MSYS-bashes path mangling; IOW in this case we want the /c/path/to/git
form to allow path mangling. We use $PWD instead of $(pwd), which always
has the latter form.
- In t6200, $(pwd) - the Windows style path - must be used to construct the
expected result because that is the path form that git sees. (The change
in the test itself is just for consistency: 'git fetch' always sees the
Windows-style path, with or without the change.)

This function replaces sequences of 'chmod +x' and 'git update-index
--chmod=+x' in the test suite, whose purpose is to help filesystems
that need core.filemode=false. Two places where only 'chmod +x' was used
we also use this new function.
The function calls 'git update-index --chmod' without checking
core.filemode (unlike some of the call sites did). We do this because the
call sites *expect* that the executable bit ends up in the index (ie. it
is not the purpose of the call sites to *test* whether git treats
'chmod +x' and 'update-index --chmod=+x' correctly). Therefore, on
filesystems with core.filemode=true the 'git update-index --chmod' is a
no-op.
The function uses --add with update-index to help one call site in
t6031-merge-recursive. It makes no difference for the other callers.

When tests are run in parallel and a few tests fail, it does not help
that the output of the terminal is totally confusing, as you rarely know
which test which line came from.
So introduce the option '--tee' which triggers that the output of the
tests will be written to t/test-results/$TEST.out in addition to the
terminal, where $TEST is the basename of the script.
Unfortunately, there seems to be no way to redirect a given file
descriptor to a specified subprocess in POSIX shell, only redirection
to a file is supported via 'exec > $FILE'.
At least with bash, one might think that 'exec >($COMMAND)' would work
as intended, but it does not.
The common way to work around the lack of proper tools support is to
work with named pipes, alas, one of our most beloved platforms does not
really support named pipes. Besides, we would need a pipe for every
script, as the whole point of this patch is to allow parallel execution.
Therefore, we handle the redirection in the following way: when '--tee'
was passed to the test script, the variable GIT_TEST_TEE_STARTED is set
(to avoid triggering that code path again) and the script is started
_again_, in a subshell, redirected to the command "tee".

This patch makes --valgrind try to override _all_ Git binaries in the
PATH, and it makes it an error to call *.sh and *.perl scripts directly.
While it is not strictly necessary to look through the whole PATH to
find git binaries to override, it is in line with running an expensive
test (which valgrind is) to make extra sure that only binaries are
tested that actually come from the git.git checkout.
In the same spirit, we can test that neither our test suite nor our
scripts try to run the *.sh or *.perl scripts directly.
It's more like a "because we can" than a "this is tightly connected
to valgrind", but in the author's opinion "because we can" is "so we
should" in this case.

This patch adds the ability to use valgrind's memcheck tool to
diagnose memory problems in Git while running the test scripts.
It requires valgrind 3.4.0 or newer.
It works by creating symlinks to a valgrind script, which have the same
name as our Git binaries, and then putting that directory in front of
the test script's PATH as well as set GIT_EXEC_PATH to that directory.
Git scripts are symlinked from that directory directly.
That way, Git binaries called by Git scripts are valgrinded, too.
Valgrind can be used by specifying "GIT_TEST_OPTS=--valgrind" in the
make invocation. Any invocation of git that finds any errors under
valgrind will exit with failure code 126. Any valgrind output will go
to the usual stderr channel for tests (i.e., /dev/null, unless -v has
been specified).
If you need to pass options to valgrind -- you might want to run
another tool than memcheck, for example -- you can set the environment
variable GIT_VALGRIND_OPTIONS.
A few default suppressions are included, since libz seems to trigger
quite a few false positives. We'll assume that libz works and that we
can ignore any errors which are reported there.
Note: it is safe to run the valgrind tests in parallel, as the links in
t/valgrind/bin/ are created using proper locking.

Many test scripts assumed that they will start in a 'trash' subdirectory

On multiprocessor machines, or with I/O heavy tests (that leave the
CPU waiting a lot), it makes sense to parallelize the tests.
However, care has to be taken that the different jobs use different
trash directories.
This commit does so, by creating the trash directories with a suffix
that is unique with regard to the test, as it is the test's base name.
Further, the trash directory is removed in the test itself if
everything went fine, so that the trash directories do not
pile up only to be removed at the very end.
If a test failed, the trash directory is not removed. Chances are
that the exact error message is lost in the clutter, but you can still
see what test failed from the name of the trash directory, and repeat
the test (without -j).
If all was good, you will see the aggregated results.
Suggestions to simplify this commit came from Junio and René.
